BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a windshield wiper blade sharpener device, and more particularly to a portable windshield wiper blade sharpener device for easily cleaning or sharpening the windshield wiper blades.

2. Description of the Prior Art

Typical windshield wiper blades are provided to move over and to clean outer surfaces of windshields of vehicles. After using, or after being hardened by sunshine for a period of time, the windshield wiper blades may be hardened and/or broken, and thus may not be used to effectively clean the windshields.

For allowing the windshields of the vehicles to be suitably cleaned by the windshield wiper blades, the windshield wiper blades should be cleaned or sharpened from time to time, in order to remove the hardened portions or parts of the windshield wiper blades.

For example, U.S. Pat. No. 3,613,318 to Gianatasio discloses one of the typical windshield wiper blade sharpener devices, and comprises a windshield sharpener attachment for attaching onto the windshields of the vehicles, and having an abrasive coated surface formed thereon for engaging with and for sharpening the windshield wiper blades.

However, the windshield sharpener attachments should be attached onto the windshields of the vehicles, and thus will interfere the field of vision of the vehicle drivers.
